SAW-HANDLE.

SPECIFICATION forming part of Letters Patent No. 270,419, dated January9, 1883.

Application tiled October 10. No model.

To all whom it may concern Be it known that I, BENJAMIN GoUL'roN, of"

- Kaco. Wangaroa, in the county of Man gonui,

in g-catch, preferably made automatic by means ofa spring, for securingsaid handle or handle socket to the end of the saw, substantially ashereinafter specified.

Reference is to be had to the accoin mnying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding partsin all the figures.

Figure 1 represents a side view of the one end portion of a erosscut-sawconstructed in accordance with the invention. Fig. 2 is a farther sideview of the same with the handle in course of being titted to its place;and Fig. 5, a side view, showing the handle as secured in position onthe end of the saw. Fig.4 is a longitudinal section, in part, on theline {U ain Fig. 3; and Fig. 5, a farther longitudinal section, in part,on the line 3 y in Fig. 3. Fig. 6 is a side view of the one end portionof apitsaw, showing a modified construction for va rying the position ofthe handle.

Although my invention is only shown in the drawings as applied to theone end of a saw, it will readily be understood that both ends are ormay be alike.

Theinvention is more particularly intended for crosscut saws, but, asalready stated, is also applicable to other saws.

The handle is mainly constructed of thin metal plates, and slips ontothe end of the saw or receives the end of the saw within it as otherloose handles of crosscnt-saws have been fitted; but it importantlydiffers in the means Patented in New Zealand Mart-h 6, 1882, No. Go].

provided for attaching it to and detaching it from the saw.

Referring in the first instance to the first five figures of thedrawings,either end portion of the saw A has a slot, I), cut or formedin it from the front edge of the saw toward the back thereof, or atright angles to the length of the saw, thesame presenting an open endwhere it joins the cutting-edge of the saw. It also has another, anditmay be smaller, open outer ended slot, 0, formed in its edge andrunning in direction of thelength of the sawylikewise has a shoulderprojection, s, on said end edge between the slot 0 and the back edge ofthe saw.

B is the handle or metalsocketportion thereof, constructed atits innerend to slip over or receive within it the end of the saw, and providedat its back or outer end with the usual hand-gri ppingcross-bar (I. Saidhandle-socket is provided at itsjaw or sawreceiving end with acrossrivet or pin, 0, arranged to fit or play within the slot I) when thewhole handle is being fitted to its place, as shown in Fig. 2. The wholehandle then turns by this pin 0 as a pivot within and against the backend of the slot 1) till it is brought into its proper closed positionrelatively to the end of the saw, as shown in Fig. 3, when it is securedor locked byacrosspin or proiection, on a slide, 0, shootingintoengagement with the slotc in the end edge portion of the saw. The slide0, which carries the pin j", that works through and along a slot, g, inthe.handle-socket 13, is fitted to hug the outsides of said socket, andis connected by a cross-pin, It, which passes through another slot, 1',in the socket and serves as a bolster for a spring, 7;, to press againstand urge the slide (J forward. In this way the whole handle be comesself-locking, as it is adjusted into position, by first entering the pin0 within the slot 1) and turning the handle up till it is arrested bystriking the shoulder projection s. In the working of the saw there willhe no tendency of the handle to get loose, as the strain comes entirelyupon the pin 6 and not upon the slide U or its locking-pin], and bysimply drawing back the. slide 0 the whole handle, on being presseddown, is readily detached from the saw when required.

By the construction of the handle and end of the saw, as described, thehandle becomes self-adjusting in its lit to the. saw, and the spring 7.not only provides for its being selflocking, but for holding itin place.ltd'esired, said spring might be dispensed with, and the slide C he slidforward by hand and be secured by a set-screw or otherwise from slippingback. A spring-catch, however, which the slide with its locking-pin andspring forms. is preferable.

Fig. (i of the drawings shows the end ot a pit-saw, A, as formed withduplicate slots 1; I, the one of which projects inward from the cutting-edge of the saw, and the other from the back edge thereof; alsoshows duplicate slots 0 c in the end edge ol the saw, with the shoulderprojection a between them. This construc tion provides tor the handle'3, with its accompanying slide (fl, and pins 0 f being attached closereither to the front or back edge of the saw, as the work ma. require.

Having thus described my invention, what I claim as new, and desire tosecure by letters Patent, is

1. The saw ldade A, having a shoulder, s, and slot 0 in its end, a slot,1), in its side, and the ad acent corner cut away, ha ring; the cornerot' the. blade of the saw curved in the are of a circle from the innerend of slot I) as a center, as and for the purpose specified.

2. The c mbination, with the saw ;\,|l'|\"lll a shoulder, J, an endslot, 0, a slide slot, 1), and the adjacent corner rounded. ol' thehandle or socket ll,providedwith the fixed pin 0,11 sliding pin.f, and ashoulde adapted to lit shoulder J at the same time that said pins eandffit in the slots I; and 0, respet'atively, as and For the pur 'iosespecified.

J). The combination, wi h the .raw or saw blade A, having open-endedslots I 0, arranged at right angles to 621,011 other, or thereabout, asdescribed, ot' the handle or handle-socket I provided with a cross-pin,for fit within the slot 1) ol' the saw, and a spring-catch, C. arrangedto engage with or in the slot (5 ot the saw, substantially as specified.

The foregoing specification ot' my improvea meat signed by me this 2lstday of July,'l882.
